How this calculator works
Estimate 4K export file size and upload duration from bitrate. Planning estimates only — verify measurements independently. Size MB = duration × bitrate ÷ 8; upload from Mbps. Example: 10 min 4K @ 50 Mbps → ~3.7 GB; upload time from your Mbps.
Size MB = duration × bitrate ÷ 8; upload from Mbps.
Example: 10 min 4K @ 50 Mbps → ~3.7 GB; upload time from your Mbps.
When to use this 4K Video File Size & Upload Time
